Accupro 95168343 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 95168343 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch diameter with a 0.0150 inch corner radius, a 4-flute spiral geometry, and an AlTiN coating that provides heat resistance and extended tool life at elevated cutting speeds. The right-hand flute direction and right-hand cutting geometry are standard for conventional CNC and manual milling setups. At 2-1/2 inches overall length with a 3/4 inch length of cut, it fits common toolholders and collet chucks used in production and job shop environments. This tool is installed and operated by machinists and CNC programmers working in precision metal fabrication.

This end mill is suited for milling ferrous and non-ferrous metals where a corner radius profile is required to reduce stress concentrations or produce blended corner features. The centercutting design allows for plunge entry, making it versatile for slotting, profiling, and pocket milling. The variable helix geometry helps reduce chatter and harmonic vibration during aggressive cuts. The 1/4 inch shank diameter accommodates standard ER collets and end mill holders commonly found in CNC machining centers and manual knee mills.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating extends tool life in high-temperature cutting conditions
• 0.0150 inch corner radius reduces corner chipping and stress concentrations in finished workpieces
• Variable helix flute design reduces vibration and improves surface finish
• Centercutting capability allows direct plunge entry without a pilot hole
• Right-hand cut, right-hand spiral geometry compatible with standard CNC spindle rotation

Compatibility

Designed for use in standard 1/4 inch ER collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual milling machines requiring a single-end corner radius end mill with a 1/4 inch shank.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for toolholder torque and runout specifications. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Verify that cutting parameters such as feed rate and spindle speed are appropriate for the workpiece material and AlTiN coating before starting the cut. Do not exceed the rated length of cut of 3/4 inch when side milling under full depth conditions.
